Theodor Jacobsen Observatory

Theodor Jacobsen Observatory is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Theodor Jacobsen Observatory rather than just read about it. In short: The Theodor Jacobsen Observatory (TJO) is the on-campus observatory of the University of Washington. Built in 1895, it is the second oldest building on campus and was constructed using the remaining Tenino sandstone blocks from Denny Hall, the oldest and first building on campus.

Key takeaways

Theodor Jacobsen Observatory belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Theodor Jacobsen Observatory to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Theodor Jacobsen Observatory from memory before moving on to harder problems.

Reference excerpt

The Theodor Jacobsen Observatory (TJO) is the on-campus observatory of the University of Washington. Built in 1895, it is the second oldest building on campus and was constructed using the remaining Tenino sandstone blocks from Denny Hall, the oldest and first building on campus. The refracting telescope, enclosed within the dome, has a six-inch Brashear objective lens of a Warner & Swasey equatorial mount. The observatory also includes a transit room on the west side, and a 45-seat classroom that was built as an addition in 1912, on the south side. Today, the observatory is primarily used for public outreach and is run jointly by the UW Department on Astronomy and the Seattle Astronomical Society. Every first and third Tuesday between April and September the observatory is open to the public. The observatory is listed on the State Register on Historical Buildings. Information on the original design and building of the observatory by Prof. Joseph Marion Taylor may be found on the University Washington Astronomy Department website and other sources.

Worked examples

Example 1 — a first encounter with Theodor Jacobsen Observatory

Start with the simplest possible case. Write down what Theodor Jacobsen Observatory claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Theodor Jacobsen Observatory before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Theodor Jacobsen Observatory ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Theodor Jacobsen Observatory

In research: Theodor Jacobsen Observatory appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Theodor Jacobsen Observatory in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Theodor Jacobsen Observatory is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1895 establishments in Washington (state), American astronomical observatory stubs, Astronomical observatories in Washington (state), so understanding it makes those chapters shorter.
In everyday life: Look for Theodor Jacobsen Observatory outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
